You say hello in a voice room and hear yourself say it again half a second later. Or a high-pitched whine builds until everyone leaves. Or people tell you there is a constant hiss under your voice, like an old cassette. Three problems, three causes, and almost always a free fix.
Echo in voice chat: it is usually someone else’s speakers
The first instinct is to blame your own microphone. Resist it. When you hear your own voice coming back with a short delay, the cause is almost always another person in the room. Your voice plays through their speakers, their mic picks it up, and it gets sent back to everyone. You are the one who notices, because it is your voice.
A simple rule of thumb: if you hear your own echo, look at the others. If other people hear themselves when they talk, the loop is probably on your side.
The three problems sound quite different:
- Echo: your words come back, clear, a fraction of a second late.
- Mic feedback: a squeal or howl that grows on its own, usually when a speaker and a mic sit close together.
- Hiss: a steady background “shhh” that stays even when nobody is talking.
Headphones: the cheap fix that solves most of it
Echo needs two things: sound coming out of a speaker and a mic close enough to catch it. Take the speaker out of the picture and the loop is gone. Any pair of wired earbuds will do, including the ones that used to come in the box with a phone.
- Wired earbuds or headsets: the most reliable option. No delay, no battery, nothing to pair.
- Bluetooth headphones: they stop echo too, but many models switch to a low-quality “hands-free” mode when their mic is in use, and you start to sound like a phone call from 2005. If that happens, keep the headphones for listening and use your computer’s built-in mic.
- Bluetooth speakers and soundbars: the worst combination. The sound is loud and delayed, and browser filters struggle to remove it.
Browser echo cancellation and noise suppression
Modern browsers can cancel echo, suppress background noise and adjust your mic level automatically. These filters switch on when a site asks for them as it opens your microphone. They fail when speakers are very loud or when audio goes through an external device that adds delay, because the filter no longer recognises the sound it should subtract.
Chrome and Edge
There is no visible switch for these filters, and that is fine. What you can check: click the icon to the left of the address bar, open the site settings, and make sure the right microphone is selected.
Firefox
Firefox applies the same processing by default. If someone has been tinkering in about:config, check that media.getusermedia.aec_enabled (echo cancellation) and media.getusermedia.noise_enabled (noise suppression) are set to true. Otherwise, leave them alone.
Safari on Mac and iPhone
Safari relies on the system’s own voice processing. On an iPhone, the bottom speaker sits right next to the mic, so full volume without earbuds makes echo likely.
Hiss: input gain, mic distance and an echoey room
Hiss does not come from the others. It comes from your own setup, and there are three usual suspects.
Input gain set too high
On Windows, go to Settings, System, Sound, and open your microphone’s properties. If input volume is at 100 and a “Microphone Boost” of +20 or +30 dB is on in the classic Sound control panel, you are amplifying electrical noise as well as your voice. Bring the boost down to zero or +10 dB, set the volume around 70 to 80, and move closer to the mic instead. On a Mac, the setting lives in System Settings, Sound, Input.
Distance from your mouth
A headset mic works best two or three finger-widths from the corner of your mouth, slightly to the side so your P and B sounds do not pop. A laptop mic picks you up from half a metre away, which means more gain and therefore more hiss. The closer the mic, the lower you can set the gain, and the quieter the background becomes.
The room itself
A tiled kitchen or a bare room makes your voice sound distant and hollow. Curtains, a sofa, a bookshelf, or simply closing the door all help. Keep the mic away from fans too.
Listen to yourself before you speak
Before asking for the floor in a voice room, spend thirty seconds hearing yourself the way others will.
- On a phone: record ten seconds with the voice memo app at your usual distance, then play it back through earbuds.
- On a Mac: QuickTime Player, File, New Audio Recording, then listen back.
- On Windows: the Sound Recorder app does the same job.
Listen for hiss in the pauses, a voice that is too quiet or distorted, keyboard clatter or fan noise. One trap: the Windows option called “Listen to this device” is handy for a quick check with headphones, but left on with speakers it creates echo of its own. Untick it once you are done.
Mic feedback from two devices in the same room
This is the number one cause of the screeching that empties a voice room. You are logged in on your laptop, then you open the chat on your phone “just to check something”. Both play the room’s audio and a mic is open. The sound loops from one to the other, getting louder on every pass. That is feedback.
Common variations:
- the same room open in two tabs of the same browser;
- a tablet left connected on the coffee table;
The fix: one device per room, per physical space. If you want to switch devices, leave the room on the first one before joining on the second. And whenever a squeal starts, mute your mic straight away. It is the fastest way to break the loop, even if you are not the cause.
When it is not you: finding the source and saying so kindly
In a voice room you ask for the floor, then you talk, which makes the source easier to track down. Notice when the echo appears. If it only happens while one particular person has their mic open, you have found it.
When several people are on the mic, suggest a quick test. Each person mutes in turn while you say a sentence. Whoever’s mute makes the echo vanish has speakers too close to their mic. Most people have no idea they are sending everyone’s audio back.
A private message works far more smoothly than calling it out in front of the whole room. Something like: “Hi, I think your mic is picking up your speakers, we’re hearing an echo. Earphones should fix it.” Short, specific, friendly. If they have no earphones, they can lower the volume, move the mic away from the speakers, or only unmute when they speak.
If it carries on, the room’s creator or a moderator can step in. Usually a polite message does the job.

The ten-minute checklist for echo in voice chat
LibertiChat runs in your browser, free, with no sign-up and no download, so there is no app to configure: everything happens on your own device. In order:
- Plug in wired earbuds or a headset.
- Make sure only one device in the room is connected to the voice room.
- Pick the right microphone in the browser’s site settings.
- Set the gain: low boost, input volume around 70 to 80.
- Put the mic near your mouth and away from fans.
- Do the ten-second “listen to yourself” recording.
- Ask for the floor and check: “Can everyone hear me clearly?”
If your mic picks up nothing at all, that is a different issue, usually a blocked permission: microphone not working in your browser walks through the eight real causes. For everything else, the LibertiChat help page on mic and webcam settings answers the common questions.
Frequently asked questions
Why do I hear my own voice echo in a voice chat room?
Because someone else is listening on speakers and their mic picks up your voice and sends it back. It is rarely your own microphone. Check who has their mic open when the echo appears and kindly suggest earphones.
How do I stop mic feedback right away?
Mute your mic, then turn your speakers down. Next, check that no second device, such as a phone or tablet, is connected to the same room in the same space, because that is the most common cause.
My mic hisses. Do I need a new one?
Not necessarily. First lower the microphone boost in your system settings, move the mic closer to your mouth and keep it away from fans. In most cases the hiss goes away without buying anything.
